LIGHTING DEVICE FOR FARE-BOXES.

SPECIFICATION forming part of Letters Patent No. 361,860, dated April26, 1887. Appliefltion filed November 12, 1886. Serial No. 215E688. (Nomodel.)

To aZZ whom it may concern:

Be it known that we, GEORGE E. BROWN- RIGG and J AOOB SUTZIN, citizensof the United States, residents of the city of Minneapolis, county ofHennepin, State of Minnesota, have invented a certain new and usefulImprovement in Street-Gar Fare-Boxes, of which the following is aspecification.

Ourinvention relates to fare-boxes for streetcars and similar uses, andhas for its object to thoroughlylight up the interior of the fare boxfrom the same lamp which is used to light the body of the car.

In street-cars now in general use the three sides of the fare-box aremade of glass, and a supplementary box is built adjacent to one of theglass sides of the fare-box proper,with a smoke-tube leading to the topof the car. On the bottom of this box, or a suitable shelf in the same,is placed a small lamp, which, through the glass partition between thelampbox and the fare-box, throws an imperfect light into the fare-box.Another and larger lamp sits on a shelf near the top of the front end ofthe car and serves to light up the car.

The fare-box lamp is a constant source of annoyance. It is extremelyuncertain. It burns irregularly. The glass soon becomes covered withsmoke, and it greatly increases the risk of fire.

By our invention we dispense with the extra lamp altogether, saving theexpense and avoid ing the risk of fire, and obtain a much stronger andbetter light in the fare-box, where a good light is needed in order toenable the driver and passengers to see the fares.

Our invention consists of the device hereinafter described and claimed,reference being had to the accompanying drawings.

In the drawings, like letters referring to like parts throughout,Figures 1 and 2 are sectional elevations of the various forms of ourinvention as it appears in position for use.

A is the fare-box.

B is the car-lighting lamp resting on ashelf or bracket attached to thebody of the car.

D is a bracket-arm supported in any suitable way on the side of thefare-box opposite to the lamp B.

G is a highly-polished reflector pivotally attached to the arm D, so asto allow variation of its inclination to the Vertical plane.

I11 Figs. 1 and 2 we show a light-conducting tube, E, extending fromwithin the fare-box to above the lamp-shelf. This tube is highlypolished on the inside, and is provided with one or more lenses forcollecting and distributing the rays of light. These conductingtubeswill vary in length according to the position of the fare-box withreference to the lampshelf, the boxes in some cars being much lower thanin others. The lenses will vary according to the necessities of thecase.

K, Fig. 2, is concavo-convex, and in Fig. l we show a pair of lenses-aplano-convex at the top and a double concave lens at the bottom of thetube.

The great object is to get a strong light on the fare-dumps in thefare-box. The lenses serve to distribute the light exactly where needed.The reflector O has a concave highlypolished interior surface, and isformed as nearly as possible to the lines of exact mathematical curves.

In Figs. 1 and 2 thccurve of the reflector is an ellipse, and thelamp-flame is at one focus and the lens on top the conducting-tube is atthe other; hence the rays from the lamp will be reflected on converginglines, meeting in the top lens. The rays pass from the top lenses onconvergentlines in Fig. 1, andin Fig. 2the rays cross near the center ofthe tube, again diverging and filling the box. In Fig.1, after crossingwithin the tube, the rays are further refracted by the lens H, and passon divergent lines into the farebox. from the lens Gis below the centerof the tube, a lens of greater or less convexity being used according tothe length of the tube E.

M is a deflecting-mirror attached to the lower end of thetube E, forcatching and reflecting into the bottom of the box any scattered rays oflight that otherwise would pass off to one side into the upper space ofthe box where not needed.

We have thoroughly tested our device and find that we can get a farbetter light where needed in the fare-box than by the extra side lampnow in general use.

\Ve save the first cost of the extralamp, the

The focus of the rays and we desire protection, broadly, on all theforms shown and their equivalents; but the form shown in Fig. 1 is ourpreferred construction, and this we desire to claim specifically.

What we claim, and desire to secure by Letters Patent of the UnitedStates, is as follows:

1-. In street-cars, fare-box A, car-lamp B, conducting-tube E, providedwith collecting and distributing lens at its top, as described,

and reflector 0, arranged and supported with reference to lamp B, asdescribed, and deflector M, attached to bottom of tube E, as described,in combination, for the purpose set forth.

2. In street-cars, fare-box A, ear-lamp B, 'conducting-tube E, lens G atthe top of said tube, and lens H at the bottom of the same, reflector 0,arranged and supported with reference to lamp B,'as described, anddeflector M, in combination, all substantially as described, for thepurpose set forth.
